SPECIFICATION forming part of Letters Patent No. 655,647, dated August '7, 1900.

Application filed February 6, 1900 To all whom it may concern.-

Be it known that we, WILLIAM H. BAKER, residing at Central Falls, Providence county, Rhode Island, and FREDERIO E. KTP, residing at Moutclair, Essex county, New Jersey, citizens of the United States, have invented certain new and useful Improvements in Looms, of which the following is a specification.

This invention relates to weft or filling [O changing or supplying mechanism for looms,

and comprehends improvements in the magazine and in mechanical means controlled by the presence or absence of weft or filling in the weft-carrier and including a feeler and indicator for setting inmotion at proper times the weftsupplying mechanism.

In the accompanying drawings,which illustrate an embodiment of the invention, Fig ure 1 is a side elevation of a part of the loom, showing the lay in its beat-up position in full lines and in its retracted position at the picking-point in dotted lines. Fig. 2 is a view showing the principal parts seen in Fig. 1, but on a larger scale and in aditferent position. Fig. 3 is a plan, and Fig. 4 afrontelevation, of the feeler devices and the mechanism connected therewith for operating them. Fig. 5 is a vertical axial section of the shuttle, with the bobbin and bobbin-case in place therein. Fig. 6 is an under side view of the same, and Fig. 7 is a cross-section at A A in Fig. 5. Fig. 8 illustrates the application of a part of the invention to a shuttle wherein the bobbin-case is omitted, and Fig. 9 is a cross-section of the same at B B. Fig. 10 is a plan view of the magazine on the same scale as Fig. 1. Fig. 11 is a cross-section of the magazine on the same scale as Fig. 2.

Referring to the principal views, Ct is the loom-frame. b is the breast-beam, forming a part thereof. 0 is the vibratable lay carrying the reed and the shuttle-boxes, and d is the picker-stick. These parts are common in looms, and the moving parts may be actuated by the usual or any satisfactory mechanism.

In the loom-frame is mounted a supplying carrier or magazine 6, adapted to be rotated intermittently up to a detent or stopf by a slip-belt g or other suitable means. WVhen the lay 0 beats up, the shuttle-box hthereon Serial No. 4,221. (No model.)

at one side of the loom is brought directly under the delivery-point of the magazine 0, and when the weft or filling in the shuttle in play in said box is substantially exhausted such exhaustion of the weft or filling will set in position intermediate mechanism, whereby a dagger or tappet carried by the lay or other going part will actuate a driver to drive a bobbin-case or bobbin in the magazine down into the shuttle, the impact of the incoining bobbin-case serving to displace the exhausted case in the shuttle and force it down through the latter and out below.

The supplying carrier or magazine will be particularly described hereinafter, and We will now describe the feeler and indicator and their operating mechanism.

On the lay a, at the side of the shuttle-box h, is mounted a feeler-lever '5, adapted to swingabout a pivotal point j, and below, on. the side of the lay, is mounted a rock-shaft is, having an upright arm or prong Z, which engages an aperture in said feeler-lever, whereby when the latter is moved to and fro the shaft 70 will be rocked. The free end of the feeler-leverz' is adapted to play through a slot or aperture m in the side of the shuttlebox hand also to enter a shuttle n, which may be in the box, as will be hereinafter more fully explained. On the rock-shaft 7c is a spring 0, which tends at all times to press the feeler-lever inward toward the shuttle and. into it. Also on the shaft 70 there is a tappet-arm 19, which when the lay recedes to the picking and shuttle-receiving point is caused to impinge upon a dagger or tappet q on the loom-frame, Fig. 1, in such a manner as to rock the shaft k and withdraw-the feelerlever i from the shuttle and box. The purpose of this withdrawing device is to free the shuttle and box from the feeler devices, so as to leave the shuttle unincumbered and free to be picked and to leave the box unincumbered to receive the shuttle from the other side of the loom, as the case may be. 5 As shown herein, the dagger q plays through an aperture r in the lay c at a point therein where it will not impede the movement of the picker-stick in picking. The rock-shaft 70 has at its under side lugs s, in which is piv- 10o otally mounted a tappet t, supported by a blade-spring u to avoid too much rigidity.

The construction ofthe shuttle and the bobbin therein will now be described with especial reference to Figs. 5 and 6. In the side of the shuttle 'n, at or near its lower edge, is formed an elongated aperture, and in this aperture is pivotally mounted or fulcrumed a feeler-finger o with unequal arms.

A spring to on the shuttle bears on the shorter arm or heel of the feeler-finger and tends to hold the latter normally alined with the side of the shuttle, as seen in Fig. 6. On the longer arm of this feeler-finger the feelerlever i impinges in such a manner as to turn the finger about its pivot or fulcrum and cause its longer arm to sweep across the lower part of the shuttle. Normally when the lay is beating up and free from the dagger q the spring 0 rocks the shaft in a manner to cause the feeler-lever i to press the feeler-finger o inward to its fullest extent, as indicated by the dotted line in Fig. 6, and to also elevate the tappet p, as seen in full lines in Fig. 1. The magazine e is supported on suitable brackets 00 on the loom-frame, and on the loom-frame is fulcrnmed an elbowlever, one arm of which forms the driver y, and the other arm 2 is so formed as to be impinged upon at the proper time by the tappet I? for actuating the driver y. The manner of operation of the feeler t' to rock the shaft 70 and place the tappet t in position to operate the driver when the lay heats up will be best understood after the construction of the bobbin in the shuttle shall have been explained. The bobbin 1 is mounted in a bobbin-case 2, and this bobbin-case is held in place in the hollow of the shuttle by spring-jaws 3. There will be a pair of these jaws, by preference, to embrace each end of the bobbin-case. The manner of mounting the bobbin in the bobbincase and of mounting the said case in the shuttle is'shown and described in our pending application, Serial No. 411, filed January 5, 1900. It will only be necessary to say here that the bobbin may be held in place in the bobbin-case by spring-jaws in all respectssimilar to the jaws 3 for holding in place the bobbin-case. We may say here also that by bobbin, as the 'word is herein employed is meant any suitable form of known weft-holder. In the lower side of the hollow or tubular bobbin at its enlarged end is formed a longitudinal slot and in this slot is fulcrnmed at 4: aleverindicator 5, backed by a spring 6, which tends to press the indicator outwardand downward radially. The indicator is so curved outwardly that when pressed out to its full extent by the spring 6 it will project into the path of the feeler-finger o in the shuttle; but normally the indicator will be overwrapped by the weft or filling on the bobbin, Fig. 3, and be thus held pressed back into the slot. Now assuming the bobbin in the shuttle in play to be supplied with weft and the loom in operation, when the shuttle enters the box h at the picking-point the feeler-lever 1' will be pressed back through the medium of the dagger or tappet q and the spring w, Fig. 6, will be free to hold the feeler-finger a; back in line picking-point and the lay advances in beating up,the feeler-lever can only press in the'feelerfinger until the latter impinges upon the protruding indicator 5, which it now finds in its path. Thus the shaft 70 will be rocked and the tappet i will be put into alinement with the arm 2 of the driver y, and as the lay moves up toward the beat-up position the tappet i will impinge on said arm 2. The first effect of this will be to rock the shaft 70 until the lugs .5 come to a firm bearing on the face of the lay, and incidentally the feeler-lever 'i will be withdrawn, so as to permit the feelerfinger o to free itself from the bobbin and bobbin-case and return to its normal position in the recess at the side of the shuttle. The second and final effect will be to operate the driver y forcibly and suddenly at the moment the shuttle in the box takes a position directly I under the delivery-pointof the magazine, so

that a bobbin-case will be driven from the magazine down into the shuttle, said case displacing and knocking out the one in the shuttle. This is the position of the parts seen in Fig. 2.

The springu permits of the necessary movement of the tappet it about its pivot-point in the lugs's after the engagement of said tappet with the arm of the driver and during the subsequent rocking of the shaft 70 necessary to withdraw the feeler-lever 2' before the changing of the bobbin-cases. (See Fig. 2.)

In the principal views the invention is shown as employed in connection with a bobbin mounted in a bobbin case or box; but it may be employed as well where the bobbin is mounted directly in the shuttle.

For example, Figs. 8 and 9 show the bobbin held in place in a self-threading shuttle n by spring-jaws 6 in a known Way. It will be understood that where a bobbin-case is employed this case will be fed into the shuttle from the magazine and that. the same will be the case where the bobbins alone are changed.

The indicator 5 may be provided with a heel or shorter arm 5 back of the fulcrum, which heel projects into the hollow of the empty bobbin. The reasons for this construction are fully explained in our said pend= ing application, Serial No. 411, and they need not be repeated here. It will suffice to say When the shuttle thus IIS that the feature is not claimed herein nor is the present application limited to the use of this feature.

We will now describe the device 6, which for convenience We have called the magazine, directing especial attention to Figs. 1, 2, 10, and 11. Two pairs of sprocket-wheels 8 and 8 are mounted on spindles 9, fixed in the brackets or bracket-frames m on the loom-frame. The sprocket-wheels of each pair are conveniently connected by a hollow axle or boss, and on the pair 8 is a sheave 10, over which passes the slipping belt g. This belt is driven from a sheave 11 on the crank-skaft 12 of the loom, and it tends constantly to drive the pair of sprocket-wheels 8 in the direction indicated by the arrow thereat in Fig. 1. On the sprocket-wheels is mounted an endlesschain carrier comprising two chain 13, connected transversely by hinging-rods 1i where the links of the chains are jointed together. This chain carrier is driven through the medium of the sprocket-wheels S and drives the carrying sprocket-wheels 8. The endless carrier is here represented as moving horizontally from one pair of sprocket-wheels to the other, and this is thepreferred arrangement. The lower side of the endless carrier is supported and kept properly alined by fixed guides 15, which are supported or may be supported from the bracket-frames which carry the wheels. The bobbin-cases 2 are mounted in the endless carrier, being held in place by suitable spring-clips 16, fixed to the links of the chain. As herein shown, the clip 16 is'composed of two curved spring-fingers which take about the bobbin-case and hold it in place with sufficient firmness to prevent it from falling out. There is a clip on each link of the chain, the magazine when full carrying as many bobbin-cases as the endless carrier has pairs of links, and the driver y is by preference placed midway between the pairs of sprocket-wheels. Obviously when the driver y drives a bobbin-case 2 from the carrier down into the shuttle below, which latter will be directly beneath the driver in its beat-up position, the carrier will be moved along until the next bobbin-case of the series comes to impinge on the detent.

We are the first, as we believe, to have V invented an endless-chain magazine or carrier for weft-holders or bobbin-cases containing weft-holders and means for supplying same as needed to an active shuttle in the shuttle-box, and we therefore claim this feature broadly without limitation to specific means for accomplishing the result. Herotofore also, so far as we are aware, all feeler devices which are adapted to enter the shuttle-box have been positively actuated to move in and out at predetermined times. The novel feature of our feeler device lies in non-positive means-as a spring, for example-which tends to move the feeler-lever into the shuttle and boX normally or at all times and positive means for withdrawing said feeler-lever periodically to permit the shuttle to enter and leave the box. Being the first, as We believe, to employ such a device, we claim the same broadly and do not restrict ourselves to any specific devices for effecting the result.

Other known devices for setting in operation the supplying mechanism when the weft or filling in the shuttle is nearly or quite exhausted may be employed in lieu of that herein shown-as, for example, the electrical eX- haustion-indicating mechanism illustrated in our pending application, Serial No. 411, filed January 5, 1900.

While we have shown herein bobbin-cases containing bobbins supported in the clips or springs of the endless-chain carrier, it will be obvious that the bobbin itself-such as that illustrated in Figs. 8 and 9, for example-- may be supported in the chain, in which case a self-threading shuttle like that seen in Fig. 8 would be employed.

We have not deemed it necessary to illustrate herein a holder for the weft ends in connection with the magazine. Such holders are known, and any known form of weft end holder may be employed-as, for example, that illustrated in our pending application,

Serial No. 9,493, filed March 21, 1900.

By the phrase weft-holder as herein employed is meant any form of holder for weft or filling adapted to go into a shuttle or carrier, such as a bobbin-case containing weft, a bobbin, a cop, a butt-cop, or the like.

The embodiment of the invention herein illustrated does not contemplate supplying full shuttles, but supplying filling to a shuttle in play.
